Study of transient pool boiling of deionized water in two modes of presence and absence of a magnetic field

The transient pool boiling of deionized water was studied under saturation condition and atmospheric pressure at time periods of 1, 10, 100 and 1000s. Iron-aluminum-chromium alloy wire was used in the horizontal position as a surface heater and two permanent ceramic magnets were used to investigate the magnetic field effect on the deionized water boiling. Voltage difference on the wire heater was used to increase heat flux during periods of time, and this voltage difference increases linearly with time. The increase of heat flux was obtained by a quadratic polynomial function with increasing the voltage from zero to 50 volts over time periods. The critical heat flux with the presence of the magnetic field happens at higher superheat temperatures of wire. The critical heat flux values for periods of 100 and 1000s in the presence of the magnetic field are more than the same values in the absence of the magnetic field which could be due to the change in the chemical-physical properties of magnetized water. The magnitudes of the heat flux enhancement due to the magnetic field relative to the absence of the magnetic field for the period of 100 and 1000s were 12.74% and 7.3%, respectively.
